中文摘要：

选择性催化还原NOx是处理工业废气和稀燃汽车尾气NOx的有效方法。由于还原剂甲烷廉价易得,甲烷选择性催化还原NOx（简称CH4-SCR）已成为近年来的研究热点,而分子筛类催化剂因催化活性高而得到广泛研究。本文综述了CH4-SCR脱除NOx体系中不同金属负载的分子筛催化剂及反应机理方面的研究进展,包括Co系、Pd系、In系等分子筛催化剂在催化性能、反应机理及掺杂改性等方面的研究现状,并提出了分子筛类催化剂用于CH4-SCR的研究方向。

英文摘要：

Selective catalytic reduction of NOx is an efficient technique to remove NOx in the presence of excess oxygen for both stationary and mobile sources. Selective catalytic reduction of NO with methane （CH4-SCR） has received considerable attention because methane is low cost and easily obtained. Characterized with high catalytic activity, zeolite-based catalysts have been widely studied. In this paper, the advances in zeolite-based catalysts for CH4-SCR are reviewed, with focus on catalytic activity, reaction mechanism and the promotion effect of the main four types of Co, Pd, In and Ag catalysts supported on zeolite. By comparing the properties of these catalysts, the application and further research direction on zeolite-based catalyst of CHa-SCR are proposed.
